BATHTUB FOR SAND BATES.

The primary object of my invention is to provide a bath tub for sand baths which will hold sand about a patient imbeddcd therein in either a reclining or sitting posture, while water is .applied thereto to the point of saturation, and which will permit all excess water to drain away therefrom.

A further object is to provide a bath tub of the character described which is formed of loosely joined parts adapted to be quickly and easily assembled for use and as readily disassembled when it is to be emptied or its position is to be changed.

A further object is to provide a bath tub of the character described which is simple and inexpensive in construction.

Other objects and advantages will appear hereinafter, and whil I show herewith and will describe a preferred form of construction, I desire to be understood that I do not limit my invention to such preferred form but that various changes and adaptations may be made therein without departing from the spirit of my invention as hereinafter claimed.

Referring to the drawings which accompany this specification and form a part thereof:

Fig. 1, is view in perspective of the preferred form of my bath-tub, arranged for taking a sand bath in a sitting posture.

Fig. 2, is a vertical sectional view of a bath tub of the form shown in Fig. 1, the section being taken longitudinally through the middle of the tub.

Figs. 3, 4 and 5 are views in perspective of the various bars employed in constructing the tub.

Fig. 6, is a side view of one of the lockto hold them in rigid spaced relation to each other.

The platform 11, which forms the floor of the tub, consists of aseriesof bars or narrow planks16 of uniform length, width and thickness, placed edge to edge lengthwise of the tub and lying loosely on cross-bars 13 A plication filed November 21,1925. Serial No. 70,531.

except that transverse grooves 17, adapted to slip'over the upper edges of cro'ss bars 13, are cut in their under sides to prevent them from shifting endwise. Frames consist of parallel side-bars 18 with transverse grooves 19 cut in their upper sides, near their ends, and parallel end-bars 20 of corresponding width and thickness with similar grooves 21 cut in their under'sides, said grooves 19 and. 21 being of a width equal to that of the side-bars and end-bars respectively, and of a depth equal to half their thickness, so that when brought together, with their grooved ends interlocking, the side bars and end-bars combine to form a' comparatively rigid rectangular frame of uniform thickness. These are su-' perposed one upon another to the desired height as shown in Figs. 1 and 2, and form the walls of the tub.

In order that the frames may be held in vertical alignment, holes 22 are bored through the frames or through the bars composing the frames, in such a position as to be in vertical alignment when the frames are assembled, and a rod 23, with a pointed end 24, is inserted downwardly through the holes 22 to serve as a locking-pin. The rod may be provided with an eye or loop 25 on its upper end by which it may be handled when it is to be inserted or withdrawn.

hen the tub is adapted for the reclining posture frames of uniform length are used throughout the height of the tub. hen adapted for the sitting posture, however, frames 10 having short side-bars 18' are used at the head end of the tub to raise it to any desired height.

In either form the tub is used for holding sand about a patient under treatment. The floor of the tub is covered with several inches of sand before the patient has entered and after the patient is in position, sand is added to cover the body to the desired height. WVater is then applied to the sand until it is saturated, any excess thereof draining through the interstices between the frames 10 and between the planks 12 of the floor. When the sand is to be renewed for a later treatment, rods 23 are pulled out, frames 10 removed and planks 12 pulled apart or turned over to permit it to fall out.

Having thus illustrated and described my invention, I claim:

'1. A bath tub for sand baths comprising a platform of loose-bars supported on trestles, a series of superposed frames resting on said bottom and means for holding said frames in vertical alignment.

2. A bath tub for sand baths comprising a platform of loosely joined flat bars 'arranged side by side on tWo or more transverse trestles to serve as the bottom, a series of superposed rectangular frames resting on said platform, said frames forming the side and end Walls of the tub, and a plurality of rods extending vertically through said frames so as to hold them in vertical alignment.

3. A bath tub for sand baths comprising a plurality of parallel trestles extending transversely of the bath tub, aplatform resting on said trestles and serving as the bottom of the tub, said platform consisting of a series of flat bars loosely placed side by side so as to extend lengthwise 0f the tub, said bars having slots cut in their under sides to engage said trestles, a series of superposed rectangular frames resting on said platform and forming the side and end Walls of the tub, said frames being composed of two pairs of parallel bars grooved near their ends so as to mutually interlock, and a plurality of locking-rods extending through vertically coinciding holes in said frame whereby said frames are held invertical alignment.
